• Casefinding is a system for locating every reportable cancer case diagnosed and/or treated in a given facility or defined geographic area.
  • All cancer registries must perform case finding, including hospital-specific and central or population-based registries. Although these cancer registries may use different source documents, the procedures involved in their casefinding cycles are similar.
  • In the casefinding process, a suspense file is kept so that the status of casefinding can be ascertained at any time.
  • Casefinding can be performed electronically or manually, by active or passive means, or through a combination of methods.
  • The criteria for eligible cases in a cancer registry depend upon the governing agencies of the registry.
  • Most government agencies only require malignant (ICD-O behavior code 2 and 3) cases to be included in the cancer registry. However, hospital cancer committees or even central registries may require the registry to include benign or borderline/uncertain cases.
  • The impact of missed cases can result in underreporting the overall new incidences of cancer cases.
